Similar letters refer to similar parts in the different figures.

The object of our present invention is to provide an improved machine for rolling sheet-metal cylinders into true cylindrical form and for removing all kinks and inequalities from the surface of the cylinder.

The cylinders to be operated upon by our improved machine are first formed from sheet metal, which is joined at its edges to form a cylinder, the joints being preferably scarfjoints, which are soldered or hrazed together.

Our improved machine is especially de- 6o signed for smoothing and reducing to a true cylindrical surface the outside of copper or brass cylinders such as are usually employed. in textile manufacture in spinning or warpdressing machinery; and our invention consists in the construction and arrangement of parts, as hereinafter described, and set forth in the annexed claims.

lt is now the custom to smooth the outer surface of such cylinders by forming the cyl- 7o inder with open ends and placing itV upon a heavy horizontal arm adapted to pass through the cylinder andA support the same upon its upper surface, which is curved with a curvature either equal to or somewhat less than the 7 5 curvature of the cylinder, and then rolling the outer surface of the cylinder by means of a small roll,which is made to travel back and forth across the out-ersurface of the cylinder in a parallel direction with its aXis,and at the 8o same time applying pressure to the roll to compress the sheet of metal of which the cylinder is composed between the roll and the upper curved surface of the horizontal arm.

This method is effectual in smoothing the at each movement is confined to the narrow path running lengthwise the cylinder. By the use of ourimproved machine the smoothing-roll is moved slowly lengthwise the cylinder while the cylinder is being rotated, so

that the pressure is applied in a spiral path loo By 9o versely to the I-beam F.

running around the cylinder from end to end, and the cylinder when finished is not only smooth upon its outer surface, but it is found to vbe rolled into true cylindrical shape, so that when the cylinder is mounted with suitable heads upon a revolving shaft it will turn with approximate accuracy, due to its outer surface being closely concentric with its axis of rotation.

The machine represented in the accompanying drawings as embodying our invention consists of three upright housings A, B, and C, in which is journaled a strong horizontal shaft D, carrying a drum D', upon which the cylinder to be operated upon is mounted. The housings A and .B are maintained in a Xed position and supporta driving mechanism bywhich the shaft D is rotated. Power is applied to rotate the shaft D through a belt-pulley E, attachedk to a short countershaft E, carrying a pinion E2, which engages the gear E3 on the shaft D.

Between the housings B and C is an, I-beam F, hinged at one end to the block F', which 'is capable 'of being adjusted in vertical ways F2 in the housing B by means of the serewG, which is held from vertical movement in the housing and enga-ges a screw-thread in the block F. The opposite end of the I-beam F is detachabl y connected by a pin F2 with the block F4,which is adjustable in vertical ways F5 in the housing C by means of a screw G, held from Vertical movement in the housing and entering a screw-thread in the block F4, so that the rotation of the screws G and G' will raise or lower the I-beam F. The screws G and G are provided with beveled gears G2 and G3, which are engaged by` beveled gears G4 and G5, attached to a horizontal shaft G6. The shaft Gis made in two parts and is connected in the middle by the coupling G7. One end of the horizontal shaft G6 has a spline connection with the beveled gear G5, allowing one half of the shaft G6 to be moved endwise for the purpose of discontinuing the two halves of the shaftat the coupling G7. The opposite end of the shaft GG carries a spurgear G8, which is engaged by the pinion G2 on a crank-shaft G40, turning upon a fixed stud and provided with a crank G14.

The I-beam F forms a way for the carriage H, which is provided on `its under side with lugs H H', in which is-journaled the smoothing-roller I. The under side of the I-beam F is provided with a rack J, which is engaged by the pinion J', Fig. 11, attached to the short shaft J2, journaled in the carriage H trans- The shaft J2 is provided with a worm-gear J 5, capable of turning loosely upon the shaft J2, but connected therewith'by the clutch J4, which has a spline con- The \\'orm-gearJ3 is engaged by the worm-gear J5, carried upon and having a spline connection with the horizontal shaft J 5, journaled in bearin gs attached to the side of the I-beam F. The ends of the worm-gear J5 are inclosed by lugs J7 J7, at-

Atached to the carriage H, so that the Wormgear J5 is moved along the shaft J6 by the movement of the carriage H. The shaft J6 is driven through beveled gears J S by a vertical shaft J 9, which is connected by beveled gears J10 with the short shaft J,carrying a sprocketwheel J12, connected by a chain J12 with the sprocket-wheel J14, attached to the hub of the gear-wl1ee1 J 15, which turns upon a fixed stud projecting over the side of the housing B and is engaged by a gear-wheel J1, attached to the rotating shaft D, by which a traversing motion is given to the smoothing-roll I along the drum D. After the smoothing-roll I has moved the length of the drum it is returned by disconnecting the clutch J4 and applying a crank to the end of the shaft J2.

' The housing C is mounted upon truckwheels K, adapted to run upon the rails K', forming a horizontal track. Each of the truckwheels K turns upon the ends K2 K2 of a shaft K5, which is journaled in the housing C eccentrically with the axes of the truck-wheels K. The shaft K3 is provided with a series of holes K4 to receive a Spanner for the purpose of rotating the shaft'K2 in its bearings, so it may be turned half a revolution from the position shown in Fig. 5- to the position shown in Fig. 5n in order to bring the axes of the truck-wheels below the axis of the shaft. When the shaft K3 is in the position shown kin Fig. 5, the bottom of the housing rests upon the bed K5; but when the shaft K4 is turned half a revolution into the position shown in Fig. 5*"L the Ahousing is raised oif the bed K5 and becomes supported by the truck-wheels K. The end ofthe shaft D is journaled in a bearing in the housing C, which is closed by a removable block L, Fig. S, which allows the housing C to be released from the shaft D and moved along thev rails K for the purpose of freeing the cnd of the shaft D and allowing a cylinder'to be carried over the end of the shaft and upon the drum D' into the position indicated by the broken lines M, Figs. 1 and 2.

When it is necessary to release the end of the shaft D for the purpose of entering or removing the cylinder, the upper. horizontal shaft G6 is parted in the middle by releasing` lthe coupling G7, as represented in Fig. 3, and y as one end of the shaft G6 is supported in a bearing N in the end of a bracket N', pivoted upon the screw G', the shaft G6 is capable of being swung around the screw'G', as represented in Fig. 3. One end of the I-beam F is released from the block F4 by the withdrawal of-the pin F3, allowing the I-beam F to be swung to one side by means of its hinged connection with the block F. The removable block L in the housing C is then withdrawn, and the eccentric shaft K5 is turned from the position shown in Fig. 5 to the position shown in Fig. 5, and the housing C is then moved to one side, as represented in Fig. 3, thereby freeing the end of the shaft D.

When cylinders of smaller diameter are to be formed, they may be placed directly upon the shaft D, as represented by broken lines M', Figs. 3 and fl, and when such is the case the revolving roller instead of being held in lugs I'I' H', as shown in Fig. l, is carried in the end of an extension-arm O, Figs. 4 and l2. The drum D is provided at one end with a flange D2 to prevent the longitudinal movement of the cylinder upon the drum while it is being compressed by the smoothing-roll I. The smoothing-roll I is journaled in thelugs II' II', with its axis in a horizontal plane parallel with the horizontal plane containing the axis of the shaft D; but the vertical plane containing the axis of the smoothing-roll I is not parallel with the vertical plane containing the axis of the shaft D, it being at an angle thereto, as represented in the diagrammatic Fig. l2, where the broken line P indicates the vertical plane of the axis of the drum D' and the broken line I" indicates the vertical plane of the smoothing-roll I. The axis of the smoothing-roll I is placed at a sufficient angle to the axis of the drinn D' so that the rolling contact of the smoothing-roll I with the surface of the drum will tend to carry the roller in a spiral path around the drum, said. spiral path corresponding with the pitch of the screw-thread in the worm-gear .I5 for the purpose of relieving the worm-gear from strain.

The shaft D may be supported near its center by a block R, held against the under side of the shaft D by the rods S, which are made in two parts having right and left hand screw-threaded sections connected by the right and left hand nuts S,whereby the block R may be drawn into close contact with the under side of the shaft D.

The drum D', or, in case a small cylinder is turned, the shaft D, will serve as an anvil to receive the pressure of the smoothing-roll, and the I-beam F is arranged parallel with the axis of the shaft D and in the same vertical plane and is provided with a track along which the carriage I-l moves, carrying the smoothing-roll I, lying in the plane including the I-beam F and the shaft D, so that the pressure upon the smoothing-roll is eXertedin the plane of the I-beam F.

The operation of our improved machine is as follows: A cylinder formed of ductile sheet metal,with open ends,is placed upon the drum D' in the position indicated by the broken lines M, Figs. l and 2. The removable holising C is then moved along the rails K' to bring the free end of the shaft into its bearing, the truck-wheels are raised, allowing the housing to rest in a fixed position, and the removable block L is inserted. The I-beam F is then connected with the housing C by means of the pin F3, and the horizontal shaft G6 is connected by the coupling G7. The screws Gand G' are then rotated to lower the I-beam F and bring the smoothing-roll I into contact with the cylinder at the end opposite the flange D2. Power is applied to rotate the shaft D and drum D', carrying the cylinder supported thereon beneath the smoothingroll, which bears with sufficient pressure to completely smooth the surface of the cylinder. During the rotation of the cylinder carried by the drum D the smoothing-roll I is fed along toward the flange D2 until the entire surface of the cylinder has been traversed. The shaft D and the I-beam F are then released from the housing C and the housing is moved to one side to allow the cylinder to be removed and a new one placed upon the drum D', when the operation is repeated.
